VTKIO: Skip MONOMIAL variables as they cause crashes
More efficient ordering of constrained DoF index sets
Additional test for mpi.h

Searching for mpi/mpi.h as well as just mpi.h autodetects the mpi packages on
current Debian/Ubuntu.
Merge branch 'master' of github.com:libMesh/libmesh
Removed incorrect assert in equation_systems.C. Assert is no longer valid now that we can plot a subset of the systems in an EquationSystems object.
Fix for --enable-mpi --disable-petsc cases

oops - did not complete enablegccdebugging -> enableglibcxxdebugging replacement.  done now
Merge pull request #5 from robert-we/master

Workaround crash when using MONOMIALs and VTKIO
warn rather than skip silently.
Don't double-add libmesh_*FLAGS when profiling
Misc example 2 needs a command line argument

This must have been stripped somehow during the transition to
automake, then not noticed because it's only active for
--enable-complex
update .gitignore
update .gitignore
slepc example ignores too
adding MeshfreeInterpolation class
adding InverseDistanceInterpolation & misc_ex8 to demonstrate usage
adding nanoflann as a contributed package.

nanoflann is a BSD-licensed C++ header-only library for building
KD-Trees, mostly optimized for 2D or 3D point clouds. Queries for
neighbors around any arbitrary location in space can then be solved
quickly and efficiently using Approximate Nearest Neighbor (ANN)
algorithms.
